Embodiment Construction

[0014] The specific implementation manner of the present invention will be described below in conjunction with the accompanying drawings.

[0015] Such as figure 1 Shown, a kind of tailings dehydration novel process of the present invention is characterized in that comprising the following steps:

[0016] 1) First feed the tailings into the cyclone, the grit of the cyclone is fed into the dewatering screen, and the overflow of the cyclone is fed into the thickener,

[0017] 2) The under-screen product of the dehydration sieve is returned to the cyclone, and the over-screen product of the dehydration sieve is the final product with a water content of 14%-16%.

[0018] 3) The overflow of the concentrator is fed into the clarifier, and the underflow of the concentrator is fed into the filter press.

[0019] 4) The water separated from the clarification tank is reused, and the bottom flow of the clarification tank is fed into the filter press,

[0020] 5) The filtrate of the fi...

Abstract

The invention relates to the technical field of mineral separation, in particular to a novel tailings dewatering process which is characterized by comprising the following steps of: firstly, feeding tailings to a swirler, feeding settled sand of the swirler to a dewatering screen, feeding overflow of the swirler to a thickener, and returning undersize products of the dewatering screen to the swirler, wherein the undersize products of the dewatering screen are final products with water content of 14-16 percent; and feeding the overflow of the thickener to a clarifier, feeding underflow of the thickener to a filter press, recycling water separated from the clarifier, feeding the underflow of the clarifier to the filter press, and returning filtrate of the filter press to the thickener, wherein filter cakes of the filter press are final products with water content of 9-10 percent. The invention can realize tailings online dewatering, thereby saving funding, enabling the tailings to be directly used online, ensuring the smooth operation of subsequence works, and being beneficial to the environment protection and the production safety.

Description

technical field [0001] The invention relates to the technical field of ore dressing, in particular to a new tailings dehydration process. Background technique [0002] At present, the tailings treatment method is "thickener concentration, tailings dam storage". This method requires a large space for tailings storage, many operators and maintenance personnel, inconvenient production management, and huge direct or indirect investment. Especially in recent years, with the continuous development of tailings reuse, there is an urgent need for a new process so that tailings can be directly used online without entering the tailings dam. Contents of the invention [0003] The purpose of the present invention is to provide a new technology for tailings dehydration that can save money, realize online dehydration of tailings, ensure smooth progress of follow-up operations, and be beneficial to environmental protection and production safety. [0004] The purpose of the present invent...
